No. VIII. — Further Compaeison of the Hip Joint and Knee Joint 

 Muscles in the Ceecopithecus, Cynocephalus, and Macacus. 



Since publishing in Notes I. and II. my earlier observations on the 

 muscular mechanism of the hip joint in Man and some of the lesser 

 Monkeys, I have made further observations on this subject, a summary 

 of which seems to me worthy of being laid before the Academy. 



loped, the member so characteristic of the human hand seems in the most elevated apes 

 (the Orangs) to incline to a complete annihilation. These apes, therefore, have nothing 

 in the organization of their hand which indicates a passage into the human form ; and I 

 insist in my memoir 'on the profound differences revealed by the study of the movements 

 in hands formed to accomplish objects of a totally distinct order. A close examination 

 of the muscles of the arm and shoulder in the pretended anthropomorphous apes confirms 

 these results. Besides, it is especially in the ape in appearance the most like man — the 

 Indian Orang — that the hand and foot present the most striking degradations. This 

 paradox — this default in the parallelism in man and the large apes in the developement 

 of correlative organs, such as the brain and the hand — shows absolutely that other 

 harmonies and other destinies are here in question. 



" The facts upon which I insist permit me to affirm, with a conviction founded on a 

 personal and attentive study of all at present known, that anatomy gives no grounds for 

 the idea, so violently defended now-a-days, of a close relationship between man and ape. 

 One may invoke in vain some ancient skulls, evident monstrosities, found by chance, 

 such as that of Neanderthal — and here and there similar forms may now be found ; 

 they belong to idiots. One of these Avas discovered a few years ago by Dr. Binder, who, 

 at the request of M. Mace, presented it to me. It is now in the collection belonging to 

 the Museum, It will henceforth be counted among the elements of the great discussion 

 on the nature of man which now agitates philosophers and troubles consciences ; out 

 of which discussion, some day, the divine majesty of man shall arise consecrated by com- 

 bat, and ever henceforth be inviolable and triumphant."
